Access to appropriate and high quality health care is one of the most important ways to reduce maternal and infant mortality. This study evaluates the quality of care during childbirth, the effective factors, and promoting strategies in Lorestan province, Iran. This research is a mixed explanatory study (i.e., quantitative and qualitative). The quantitative part is descriptive-analytic. The quality of 200 care processes during childbirth was assessed in the health centers of the province. The data were gathered through the checklists prepared according to the guidelines of the Iranian Ministry of Health. Statistical analysis was performed using SPSS software. In the qualitative part, the strategies for solving the problem were assessed through interviews with service providers, maternity administrators, and senior decision-making university officials. According to our results, the levels of care quality during childbirth were intermediate in all four phases. The lowest levels of quality in the first, second and third stages were associated with Leopold's maneuver, hand washing and pulse control, respectively. Based on the interviews, the main reasons for the reduction of care quality include lack of staff’s motivation, overcrowding and shortage of nursing workforce, low attention of officials to the Department of Midwifery, and the high burden of writing in the maternity. To improve the quality of services, the authorities in Lorestan University of Medical Sciences propose strategies such as making some incentives for care promotion. Considering the quality of care during childbirth as intermediate in all four stages in the province and investigation of the reasons indicating the lack of sufficient incentive in midwives, it is recommended that strategies such as financial incentives, greater use of private sector to reduce public sector workload, quality increase and further use of in-service training to improve the quality of services be adopted.
